Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process. A flaw was found in fuse-overlayfs, a component used for rootless containers. This vulnerability allows a low-privileged process to retain SUID (Set User ID) and SGID (Set Group ID) permissions on files after they are truncated or opened with the O_TRUNC flag. This can enable a local attacker to manipulate file permissions, potentially leading to privilege escalation within the system.
